Bayer in Radiology: About Us

Transforming Diagnostic Imaging Insights into Innovations

Bayer HealthCare Medical Care has its roots in radiology. Its commitment to imaging began more than 75 years ago, when its parent company became a contrast-media manufacturer, and continued with the integration of the Medrad portfolio of power injectors and radiology accessories. With such a foundation, Bayer has established a long tradition of bringing imaging products to the healthcare marketplace. Over the years, Bayer products have helped revolutionize imaging technology.

As a leading global supplier and trusted innovator, Bayer is committed to expanding and improving solutions for optimum patient care. We are committed to improving patient outcomes by developing innovative, cost-efficient products to help physicians quickly and accurately diagnose and treat disease.

Our growing product portfolio also includes unique technologies that refine workflow while enhancing outcomes for diagnostic radiology.



INDICATIONS and IMPORTANT SAFETY INFORMATION

INDICATIONS AND USAGE

Gadavist® (gadobutrol) injection is a gadolinium-based contrast agent indicated for use with magnetic resonance imaging (MRI):

IMPORTANT SAFETY INFORMATION

WARNING: NEPHROGENIC SYSTEMIC FIBROSIS (NSF)

Gadolinium-based contrast agents (GBCAs) increase the risk for NSF among patients with impaired elimination of the drugs. Avoid use of GBCAs in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs.

  • The risk of NSF appears highest among patients with:
    • - Chronic, severe kidney disease (GFR <30 mL/min/1.73m2), or
    • - Acute kidney injury
  • Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (for example, age >60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing.
  • For patients at highest risk for NSF, do not exceed the recommended GADAVIST dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration.

Contraindication and Important Information about Hypersensitivity Reactions: Gadavist® is contraindicated in patients with history of severe hypersensitivity reactions to Gadavist®. Anaphylactic and other hypersensitivity reactions with cardiovascular, respiratory, or cutaneous manifestations, ranging from mild to severe, including death, have uncommonly occurred following Gadavist® administration. Before Gadavist® administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and/or allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to Gadavist®.

Acute Kidney Injury: In patients with chronic renal impairment, acute kidney injury sometimes requiring dialysis has been observed with the use of some GBCAs. Do not exceed the recommended dose; the risk of acute kidney injury may increase with higher than recommended doses.

Extravasation and Injection Site Reactions: Ensure catheter and venous patency before the injection of Gadavist®. Extravasation into tissues during Gadavist® administration may result in moderate irritation.

Overestimation of Extent of Malignant Disease in MRI of the Breast: Gadavist® MRI of the breast overestimated the histologically confirmed extent of malignancy in the diseased breast in up to 50% of the patients.

Adverse Reactions: The most frequent (≥0.5%) adverse reactions associated with Gadavist® in clinical studies were headache (1.5%), nausea (1.2%) and dizziness (0.5%).
